Appueatitn mea December 7, 1915. serial No. 65,464.

To all 'whom it may concern Be it known thatv I, SAMUEL M. HERBER, a citizen ofthe United States, residing at Inza, in the county vof Buchanan and State of Missouri, -have invented certain new and useful Improvements in Oil Distillation; and I do hereby declare the following to be a full, clear, and exact description ofthe in- .vention, such as will enable others skilled in the art to which it appertains to makel and use the same.V

My invention relatesto oil distillation and represents a further development of my former work and it ,consists of certain lfeatures which will be hereinafter fully described and claimed.

The prime object of my invention, among others, is to provide means for the distillation of oil combined with any form 4of lime with or without the use of air, air`r and steam, or steam alone,`with or without pressure, andthe employment ofan apparatus consisting primarily of special form of retort which latter may be readily rotated either wholly or partially and periodically or continuously. The object, therefore, which I have attainedy in providing a rotatable retort is to enable the operator to present as desired, a new or clear surface of the retort to the heat agency whereby the deposited carbon and particles of lime will ad,l

here to the walls of the retort at the point where the heat has been applied and whlch lcan subsequentlybe readily removed as may be found necessary.

- The object of my present invention, therefore,` consists in being able to produce a lower boiling point hydro-carbon, from oil commingled with lime, by thus being able to readily apply at will the requisite degree of heat, thereby causing the carbon. and a. certain portion of thelime to become caked or burned fast to the walls of the retort whereby the deposited carbon may be subsequently and .readily removed from the retort-and insuring that subsequent charges f of oil and lime may be quickly introduced into the retort, thus rendering the distilling operation practically continuous except the few intervals made necessary by thc removal of the accumulated carbon and lime adhering to the wall of the retort.

A further object of my invention, among others, is to provide a retort which may thus be readily wholly or partially rotated in either direction and provided with devices viousl for the introduction of thevoil, lime, steam and air and the free escape of the products of distillation. i v

Other objects and advantages will be hereinafter made clearly apparent by reference to the following specification, considered in connection with the accompanying drawings, in which,

Figure l shows a longitudinal, central,

sectional, view of-my retortl complete, ready for use. Fi'g. 2 is a transverse, central, sectional view thereof, showing a portion of the base partly broken away.

In materializing my invention, I provide a suitable support of base land upon the upper side thereof, I form a housing 2, within which I rotatably mount my ,retort 3, whereby the retort may be wholly orpartially rotated at will. The retort is preferably lcylindrical in cross section, though oby any preferred form of contour may be employed as octa'gonal, square and the -like and upon each end of the retort, I provide the tubular extensions or hollow trunnions 4, the outer ends of which are supported 'by the casings 5, each having a bore 6 to correspond with and receive the ends of said trunnions, it being understood that a suitable stuffing box 7 is provided between l'said parts to prevent leakage, as will hereinafter be made obvious. Below the retort, I have also provided a perforated pipe 17, leading to any suitable source of supply of gas or gases, or other form of fuel, whereby the retort may be heated to the desired degree. It will be observed that I am enabled to introduce the oil into the retort through the mediation of the delivery pipe 18 which extends through a suitable stuffing box 19, or equivalent device designed to prevent leakage in the outer end of the pipe section 20 which latter extends retort by means of suitable formation of the parts thereof and outward at the opposite end to receive the controlling handle 2l whereby the pipe 20 may be easily rotated in either direction. The oil delivery pipe communicates with the central portion 22 of the pipe 20 by passing through the 'partition wall or plug 28 whereby the annular chamber 24 is formed around said delivery pipe. The middle portion 22 is provided with a plurality of perforations as shown and is also formed with the partition wall or plug 25 whereby the oil will be confined within the central perforated portion and entirely through the' vessel is to receive the oil through the per t'orations in `the section 22 and thus insure that the oil as it overiows from the vessel 26 will be distributed uniformly over the lower portion uof the bottom of the retort.

In order to accomplish the rotation or partial rotation of the retort, I provide suitable supports, as the wheels 8 mounted 1n an suitable manner, as upon the journals 9 pre erably. provided with ball bearings not shown. The bearings receiving the trunnions 9 are preferably formed with the two upwardl extending arms 10, each having an Vantiriction wheel or roller 11 designed to bear against the contiguous part of the retort, which latter is provided with the annular track way l2,l designed to coperate with the wheels 8, the said track ways being so mounted as to prevent longitudinal movement of the retort.

Upon one of the hollow journals or tubular extensions 4 of the retort, I secure the gear 13, designed to cooperate with the driving worm 14 whereby the retort is easily turned intermittently or continuously 1n either direction. The housing 2 is of such formation as to provide an annular vchamber 15 around the exterior walls of the retort and I also provide a suitable flue opening 16for the products of combustion.

Lime may be readily introduced into the retort through the manhole 28 and, the deposited carbon, lime, etc., may also be easily removed from the retort through said manhole, as will be obvious. I also provide the delivery pipe 29 whereby steam may be readily introduced into the retort and delivered therein through the perforated delivery section 30, as will be readily apparent. It will also be obvious that I have provided means for the escape of the vapors incident to the process of distillation, inasmuch as I have secured the perforated pipe member 31 connecting at one end with the annular chamber 24 and at the other with the annular chamber 32, thus insuring that the said gases or vapor may pass through the perforations 33 upward through the pipe sections 34 extending into the chambers 35, thence escaping upward through the pipes 36 and the pipes 37 leading to the condenser 38, it being understood that after condensation of the vapor, the products of condensation will be delivered into the receiving tank 39 or other receptacle provided therefor. It is also obvious that any heavier particles arising through pipes 34 will pass downward from the chamber 35 through the annular space 40 and into the opening 6 and thence through the hollow journals 4 back into the retort.

It will be observed from the foregoing that I am enabled to readily and reliably carry out my improved method of oil distillation, employing commingled oil and lime and the introduction of steam or air with or without pressure and making it possible-to prolong the distillation process without shutting down the retort as when it is neces- 'sary to clean out the accumulated lime and carbon residuum burned to the walls of the retort, and I` am at the same time able to facilitate the formation of the lower hydrocarbons by increasing the rate of formation which is possible by presenting a new fresh surface of the retort to the heat action and I am furthermore thus enabled to conserve and apply to the best possible advantage the heating units, also to eliminate the danger of overheating the retort, and consequently the danger of explosion incident thereto, in distlling oil commingled with lime.

As a support for the parts 5, I prefer to provide a resilient form of support and I have shown this form of construction consistng of a suitable base 41 upon which I erect the socket member 42, within which I dispose the standard 43, the upper end of which I provide with the recess, 'designed to receive the lower portion of a ball 44, the said standard being supported within the socket by a compression spring 45 as clearlyv presented inlFig. 1 of the drawings. The lower portion of theparts 5 being formed with a downward extending section 46 hav ing a recess to receiveA the upper portion of 'the ball 44, will insure through the resiliency resulting from the use of the springs 45, that the requisite yielding form of support will be provided for the extreme outer ends or journals of the still, and permit thel free, complete, or partial rotation thereof in either direction at the will of the operator.

Believing lthat the advantages, construction and manner of using my invention have thus been made clearly apparent, and the method or process employed needs no'further' explanation, further reference is deemed unnecessary.

What I claim and desire to secure by ILetters Patent is:

1. The herein described method of..producing a lower boiling pointhydro-carbon from oil commingled with lime, consisting of distlling the commingledmass in a retort, rotated or oscillated intermittently or continuously whereby a fresh interior surface of the retort walls is presente'd to the heat action, during the distlling operation.

2. The herein described method of producing a lower boiling point hydro-carbon from oil commingled with lime, into or through which steam or air, or both is introduced, consisting in distlling the commingled mass in a retort rotated or oscillated intermittently or continuously, operating either under pressure or without pressure, 13o

whereby another fresh the retort wall is interior surface of presented to the heat action, during the distilling process. v 3. The herein described method of producing from oil commingled applying heat directly face of the retort the d rotating or oscillating a lower boiling point hydro-carbon with lime, consisting in to a part of the suresired time and then the retort to present another part of the surface thereof to the 10 direct heat action.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
